To atl whom it 'may concern:

Bel it known that I, GUs'rAvn LANGBEIF, a citiaen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Leaf or Pocket for Fly-Books, of'

which the following is a specification.

My invention relates to a new and useful fly boek and consists of a leaf having a back and two front sections suitably connected thereto with their adjacent edges movable with respect to said back and independently of each other.

It further consists of other novel features of construction all as will be hereinafter fully set forth.

For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the `various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement a'nd organization. ofi these instrumentalities l. asherein shown and described.

'n Figure 1 represents a perspective view of a fly book in open position, showing a plurality of the leaves in position. Fig. 2 represents a perspective view of one of the leaves in detached position. Fig. 3 represents a perspective view of another form.

of leaf Similar numerals of reference indicate corresponding parts in the figures.

' Referring to the drawings: 1 designates a ily bookhaving a cover 2 and a plurality of leaves or pockets removably connected in any suitable manner with said cover which lat- .ter is also provided with a suitable means win be mad tha-the sind adjacent edges 9 and 10 are slightly spaced apart although this may not be necessary in every instance.

:I preferably provide a flap or 'closure 11,

on the back 4, which closure is adapted to be inturned over the free edges of the front sections 5 and v6 which flap serves to hold the said free edges and serves as a closure for the pocket or pockets formed between the back and the front sections, so that by turning out the Hap, access to the pocketsV may be had and by reason of the two free edges of the front sections the lingers' of the user may be easil inserted into the pockets, forcing out t e free portions of the front flaps, so that a fly 12 may be selected and removed, or any number thereof,

the backand front sections and to secure the same thereto by stitching or otherwise.

' I desire to secure the leaves in the book in any suitable manner and have here shown, as one way, the eyelets 15 carried by the leaves, for the reception of any securing means. It will be understood, however, that the leaves may be used independently of the book in which event the eyelets will be unnecessary.

In the construction shown in Fig. 3, I have shown the back 4 and the front sections-5 and G. Between the side edges and the front sections and the back I place the bellows or folds 16 which are suitably se cured thereto in order to provide for movement of the ree ends of the front sections. The bellows 16 preferably terminate a suitable distance from the free edges of the front sections in order that these portions thereof may be bent back; The back 4 is provided with the flap 11 for holding the free edges and also to serve as the closure as previously described.

It will now be seen thatI have provided a structure which is simple in construction but which enables the user to have access to the contents of the pockets.

Having thus described my invention, what desire to provide a bindingY I claim as new and desire to secure by Letters Patent, is:

l. In a leaf or pocket, a back, and a front,

the latter being formed of separate sections, each section movable with respect to the back independently of each other and being secured to the back for a portion of its extent, whereby the other portion of each section is free and the free portions of each section can be curled back independently of each other.

2. In a leaf or pocket, a back,` and a front, the latter being formed of separate sections, each 'section movable with respect to the back independently of each other and being secured for a part ofits edge to said back,

' each with its top edge and a suitable portion of its adjacent edge free from said back,

,and thev adjacent edges suitably separated,

said front sections being formed of suitable transparent material.

3. In a leaf or pocket, aback, and a front, the latter being formed of separate substantially rectangular sections, each section being Secured along two sides thereof, to the back,

Y whereby the other two sides of each section I .are free and the free portions of each section vcan be curled back independently of each other.

4. In a leaf or p0cket, a back, and a front, the latter being formed of separate sections, each section being secured along two edges thereof to said back, each with its top edge and its adjacent edge free from said back, and the adjacent edges suitably separated, said front sections being formed of suitable transparent material.

5. In a leaf or pocket, a back, and a front, the latter being formed of separate sections, each section being secured along 'two edges thereof to said back, with its top ed e and its adjacent edge free and with the a jacent edges suitably separated, said front sections being formed of suitable transparent material, and a flap movably carried by said back and adapted to be inturned over the ends of said front sections, to hold the free edges thereof and to close the pockets formed between the said front sections and said back. l
